To aZZ whom it may concern: I y Be it known that I, OwnNvD. MCF-An-LAND, a citizen ofthe United States, residing in Cliicago,\coui1ty ofCook, and State 5 of Illinois, havel invented certain new and 4usefulImprovements-in Roofing Machines,

of which the" following 'is a specication.

This invention relates to improvements in `roofing. machines andrelatesmore particnf' "larlyvto an embossing ci' print apparatus which isadapted to .be interposed 1n anyy type of paper 0I roofing machine bymerely removing two of the ooling rolls and in "serting this printingc\ofr embossing apparatus.

Among its salient objects is to provide an apparatus' having adjustablebearings by means "of Awhich the pressure roll may be.

positioned to contact the embossing roll at:

Iany desired pressure with a quick, release attachment for automaticallywithdrawing the pressure roll *without disturbing the pressureadjustments; to `provide an aparatus in j which lthe pressure andemssing rolls are geared in timed relation whereby the roofing or paperstock to be printed or embossed is fed uniformly through the embossingstage and. due to the fact that there is an excess of material main-(tained in a loop just prior to the stock being fed to the embossing vroll the print or embossing is regular and distinct; toI provide anapparatus in which the pressure roll is kept clean and prevented fromgumming and sticking to the material treated by constantly scraping itssurface and applying Water or a light cleansing substance to the surfaceof the roll; to provide an apparatus having a series of rolls quippedA410 with guide flanges so 'arranged thatv the sheet is accuratelydirected between the emboss- `ing or printing rolls; to provide anapparatus which is compact and one which accomplishes the printing andembossing of the material in a mamier superior to that 'obtained bysimilar machines heretofore in common use.

In the drawings- Fig. 1 is a side'elevation'of the apparatus with partsbroken away;

Fig is an end of the apparatus shown in Fig. 1 with parts'broken awayand parts omitted for more clearly designating the de tails of themachine; Fig. 3 1s a diagrammatic view, showing a series of coolerswiththe arrangement of the embossing machine positioned therein; Fig` 4is a plan View of a sectionvof a roof on -which the printed or embossedmater-iai hasbeen used. p e

Refeprmg to the drawings-#therooing material 1, such as a lcommon typeof felted O r fibrous materials commonyin the roofing art in themanufacture of prepared rooing, /is threaded to the' machine over theroll 2 which is geared to| a similarv guide roll 3 positioned directlybelow it. These rolls are supported on shafts 4 and .5 mounted insuitable bearings on the frame 6. The roofing material, afterI passingover the upper roll, is directed between the rolls from.

whence it dr/o'ps into ai loop, as shown at 1a. .This loop furnishes anexcess of material so that the vroofing, as it passes through theembossing rolls, will not be stretched and pulled, causing an unevenrandva iegated' design.'- 'The loop l terminate as hematerial is threadedover two flanged guide h rolls 7 and 8 mounted on shafts 9 and 10respectively, said shafts also being supported by the frame 6. Thematerial then proceeds between the embossing roll 11l mounted upon theshaft'12 and the pressure roll 1.3 mounted upon the shaft 14. Afterpassing aboutK the top of the pressure roll, the embossed material isdirected, as shown by the ar-l rows, to the adjoining cooling rolls `15shown in Fig. 3; The bearings 16 supporting the shaft 12 are mountedupon blocks 17 vertically slidable upon the supporting member 18. Thevertical movement of the blocks 17 'is acoomplished'b-y means of screws19, .which are threaded in said block andare rotated by means of theworm wheels 20 mountedupon the lowerends of the blocks and the worms 21mounted upon the shafts 22. The shafts 22 are supportedin the frame Gandare rotatable by means of hand wheels 23. On lugs 24 extending'flrornthe lower portion of the blocks 17 arelinounted rollers-25 which rideuponthe cam` wheels 26 pivoted at 27 to the framed-6. .A hand means ofthe hand wheel 23, if for any rea-. son it should be desired to releaseinstantly the pressure between the embossing and pressure rolls, thishand lever may be used. Thisvquick release is indispensable in case thematerial is not feeding properly or ing or embossing process.

Describing briefly the machine, drive power is furnished from. anyconvenient source (not shown) through the shaft 29 and transmitted Atothe embossing or printing apparatus through the pinion 30 meshingwiththe gear 31 mounted upon a shaft 32. A gear 33 also mounted upon theshaft 32 meshes through the intermediate gears` 34 and 35 with a gear 3Gmounted upon the shaft 14 on which is also mounted the pressure roll 13.y

The pressureroll 13 and the print roll 11 are driven in timed relationby meshing gears 37 and 38 mountedon the shafts 14 and 12respectively,and on the opposite side of the machine from that' on whichthe principal partof the driving mechanism is mounted. The feedrolls 2and 3 are driven by means of a. belt 39 running over pulleys 40 and 11mounted on shafts 5 'and 14, the upper roll 2 being driven from thelower roll 3 by meshing gears. Beneath the print or embossing roll 11 ispositioned a pan 42 in which is placed pigment for printing or waterwhen the rooting is to be embossed. An air pipe 43 equipped'with anozzle device plays a stream of air between' the rolls in order to keepthem freel from foreign substance during the embossing or printingoperation'. A Water jet supply throughfa pipe 44 plays upon the upperpressure roll and assistsvv in cleaning its surface. This water alsoprevents thesheet from sticking to the bed roll. g

One of the important features of the eX- plained embossing or printingmechanism is the fact that this machine is compact'an'd may be insertedin the place of two cooling rolls which are usually positionedvertically in a machine for making Waterproof felted substances such asroofing and the like. Heretofore, printing and embossing machines havebeen constructed to take `up quite an extensive floor space and areinassire in constriiction.` Also, the machine explained is equipped withflanged such as shownfat S bymeans of which the rooting sheetisaccurately guided between the printing or embossing and pressure rolls.It will benoted also thatby threading the' roofing sheet in al figure 8about the guide rolls just prior to its being fed between the printrolls the pressure feed common to most printing' machines is totallyeliminated. The elimination of the pres sure feed rolls'is an importantimprovement in that a greatdeal of difficulty caused by uneven feed andtearing of the sheet may for` be assigned to the pressurefeed rolls. anyreason has become fouled in the print,

I claim as my invention 1. In a roofing machi'ne'the combination withmeans comprising au embossing roll for imposing a design upon a roofingsheet .continuously fed therethrough, feed rolls having guidgiangesthereon arranged out of contact an in off-set relation, 'whereby thematerial is accurately fed to-tlie designmaking means without the use ofpressure..

2. In a roong machine, the combination with a means for imposing adesign upon the roofing material, .feed rolls adapted to positively feedthe material without subvjecting it .to pressure, and adapted tomaintain available at all times an excess of roofing'material to preventstrain, or deteriorationof the sheet -when the design is im* vposedthereon'. l 3. In a roofing machinethe combination lwithfa means for.imposing a design upon a froong sheet, feed rolls comprising a plurality of sets of rolls, therolls of each set being' positioned out ofcontact, guide flanges on the rolls adjacent the design im# posingmeans, whereby a loop of excess material is maintained betweenrespective sets of feed rolls, whereby differencesA in rate of .tra'velbetween' the design imposing means and the feeding means areaccommodated, and imperfections in the design and deterioration due tostrain prevented.

`" 4. In aroofing machine the combination with a means for imposing adesign on a roofing sheet, comprising a pressure'roll and la designroll, feeding means, comprising separate sets'of feed rolls inrespective sets fpositioned out of contact, guide flanges on they rollsadjacent the design-imposing means, and vertically movable means forreleasing the pressure roll from contact with the design roll, whereby aloop-of material may be maintained between the respective sets of feedrolls to compensate foi.`

differences in rate of travel..

5. In a roofing machine, the combination with'a frame, of flanged guiderolls mounted thereon and so arranged that the feed guiderolls` ofroofing stock is uniform, a pressure roll contacting with a. designimposingl roll, meansfor spraying and scraping the surface of thepressure roll, and means com-- prising a vertically movable manuallyconct'rolled means for instantly releasing the pressure roll fromcontaet.
